Penzu is an online journaling site. It looks like typing on a sheet of paper when students journal. Journals appear as grainy leather-bound books. Students can mark certain entries as private (like an updated version of folding paper over an entry). They also can insert pictures into the text. It includes tools such as email reminders to write, the ability to send tweets about your journal entries, and a variety of style customizations (such as font).
